It is true nvidia drivers are not open source, but this github page says nvidia has 248 repositories: https://github.com/NVIDIA
I'm not sure why the link was submitted today. The repo says it is 3-4 years old.
Very usable desktop experience, CUDA just works, the rest of the software ecosystem makes anything else pale by comparison (see the Pytorch ROCm discussion that made the HN front page today). Every few months I take another look at ROCm and frankly don't understand how anyone can take it seriously.
In the FOSS/Linux community the discussion around the closed source nature of desktop drivers seriously discounts the amount of FOSS work Nvidia has done.
I understand the support for AMD's in kernel drivers (and Mesa), rooting for the underdog, etc but anyone who is being honest will acknowledge there are plenty of issues with their drivers and various configurations as well.
Assuming it's six of one, half dozen of the other the fact that Nvidia drivers also bring the entire CUDA ecosystem to any GPU made in the last five years (or more) really tips the scales (overall) for the justification of an Nvidia hardware purchase (all other things being equal).
NVIDIA's business is to sell GPUs. This helps.
